rmco2003 : There seems to be a few people on here that have done similar tasks for FF7, I'm working on a translation for another game and most of its menus are stored as graphics under the name SPR. It doesn't correlate to any of the known SPR formats on the web, and the most I could find is that there are patterns of 00 hex bytes at some offsets.

I'm not really asking anyone to spend their free time hacking these files for me, but could someone point me in the right direction to working out what these files are made up of?

Alhexx : Could you maybe upload 3 or 4 of those files (e.g. on Mirex's Trashbin™).

Learning how to decode file formats isn't that easy. Even if you're familiar with data structures, it takes some experience to know what you have to look for in that file.

As I said, upload it somewhere, and I'll take a look at it.

rmco2003 : There are two types of files, one contains sprite data under the label SPR and the other contains animation data under the label ANI (I'm guessing). Here's 3 SPR files with their ANI files, and 2 SPR files without ANI files.

mirex : I was looking briefly through the data and looks like the .ANI files are quite empty (no images inside them, only some numbers, maybe animation times), and looks like that .SPR files contain multiple images inside.
